Application med March 9,- 1926. serial No. 93,407.

This invention relates to improvements in ovenfront frames, doors and cooperating parts, the objects of which will be hereinafter specific One object-of the .present invention is to so construct the oven front frame and the ovendoors that when the latter are closed, the frame and the doors are flush with each other.

A further object of the present invention is to so construct the front frame and the ovendoors als to permit the application to them of hinges which are sealed. 4

A further object of the invention is to so construct the front frame and the oven doors and to provide them with a latch that is invisible when the doors are closed.

A'further object of the invention is to so construct the said front frame and `oven doors that the whole space ofthe frame is occupied by the doors, thus eliminating the usual front cross bar between the oven doors.

Further objects of the invention will appear from the following description.

ings, A indicates the front frame, v1 the door for the upper portion ofthe oven and 2 the door for the lower portion of the oven.

Referring now to the accompanying drawi Ordinarily the upper portion is used for lare no working parts of the doors except the handles that are visible. y

The front of theframe A in cross section is approximately U-shaped as shown in F i-gures 4, 7 and 8. It comprises the front portion or leg with its outside right angular wall 4 and its inner right angular side or` leg 5. Attention is directed `to the fact that the inner leg 5 of the frontframe is made considerably deeper than the outer side or leg 4, whereby room is provided for a hinge B that is located substantially wholly within the U-shaped front frame.'

It will also be noted that thefront frame A has a depression or inwardly extending right angular V'part 6 which-is of a depth corresponding to a peripheral .flange portion 7 4, 7 Aand 8) whereby when vthe-doors are closed their outer faces are flush with the frontor face part 3 of the frame A.

Each of the doorsv 1 and 2l comprises its 4 outer face portion,` the flange or bent portion 'e' and' a leg portion 8 extending at right angles to its cuter face. The said doors comprise the outer face or panel portion formed asl described and an inner lining 9 which has a right angular part 10 that telescopes with the part8 -of the door. This lining 9 and the part 8 of the dooi` are bolted together by lbolts 11 that pass through the part 8 of the door and the. part 10 of the lining. This construction makes the door and its-lining separable. It will also be noted that the doors"are of considerably less depth than the width of the leg 5 of the frame A. By reference to Figure 4 it will that is formed on the doors 1 and 2 (Figures v be seen that the right angular portion 6 forms va step portion 12vagains't which theA flange 7 restsA when vthe door .is closed.

For the purpose of permitting of the assembling of the door, its lining and the hinge B, this front frame has its leg portion 5 pressed outward for the hinge B as shown at 13. This enables the door face or paner, the lining therefor, and the hinges B to be conveniently assembled. Furthermore the flange 5 adds strength and rigidity to the whole' frame.

The frame A as shown has its top .and side and front flanges made of a straight continuous piece, the flange 3 thereof being notched as at 14 and bent to form the angular frame. As here shown its lower part 15 is formed of a, separate angular piece, but l desire to be understood that the whole frame may be formed from a straight 4U-shaped piece which will be notched as at 14 for the purpose of enabling it to be bent in angular form. The lower piece 15 being separate, the lower ends of the flange 3 extend at the inner side of :he part 15 as shown in dotted lines and the parts are attached by means of suitable screws or bolts 16.

Referring now to the hinge construction,

` the linings 9 of the doors have their flanges 10 provided with openings 11 and suitably spot welded or otherwise secured to the in ner side of the flanges 10 of the lining is a member 17 having at its lower end an angular opening 18 for receiving the turning portion of the hinge B which will now be described.

Thehinge'compris'es a vertical member 19' that is bolted to the inwardly flared portion 13 by means of suitable fastening elements 2O which are located above and below the pintle or turning member 21. Thispintle has an intermediate and large portion 22 which is made in the form of a cam, the front and rear edges 23 ofthe cam 22 being fiat and the top and lower edges 24 being curved. The cam or enlarged portion 22 rests into an upwardly extending cavity 25 of the member 19, said member being enlarged outward as at 26 to enable the cavity to be formed. This enlarged portion 26 is provided with an opening 27 that has its 4inner end communicating with the cavity and its outer end open. Passing through this opening 27 there is an extension 28 which is round. The eX- trem'ity 29 yof the extension 28 projects beyond the outer end of the opening 27. This extension 28 receives a member 30, the opening in the said member 30 and the extension 28 being oval or angular as shown at 31, whereby the member 30 is held on the extension against rotation. Formed in the upper portion of the member 30 is an opening 32 that receives the lower end 33 of a coil spring 34, the upper end 35 of the -coil spring being attached to an integral projection 36 at the upper end of the member 19.

From the foregoing description it will be observed that the hinges are located between the inner flange 5 and the outer flange 4 whereby the said hinge is absolutely concealed. It will also be observed that the cam 22 and its 'connected parts are carried by the member 19 since the member 30 being on the outer extremity 29 holds the said cam and its parts to the member 19. The cotter pin or other device 37 may be used to hold the member 30 on the extension 29.

In operation the angular inner end 21 is in engagement with 18 of the member 17, and when the door is opened, the spring 34 pulls on the member 30 tending to close the door, and when the door is moved to its horizontal position, then the straight portions of the cam 22 will engage the straight portion 24 and lock the door'in its horizontal position, the said spring not being sufficiently strong to close the door.

In placing the door and the hinge in position with respect to the frame A, 'the door will be placedl in a vertical position in the frame and then the hinge which includes the member 19, cam 22, etc., has its angular end 21 inserted through the opening 18, when the part will `be fastened to the inwardly bulged part 13 by means of suitable bolts or other suitable elements 20. `When` the hinge portion is in place then, the angular end 21 serves to hold the door in position and all of the parts are absolutely concealed.

- For the purpose of holding the door closed an improved latch is used. This latch com prises a lever 39 which is intermediately pivoted at 40, its inner end being shaped to form a weight 41, that. holds its outer end 42 elevated, the outer end 42 carrying a lip 43 which is suitably shaped for engaging in an opening 44 that is formed in the flange 5 of the frame A. For the purpose of strengthening this opening a suitable member 45 is bolted to the flange 5 and the said members and opening registering with the opening 44. The intermediate pivotal point 40, is supported by a member 46 that depends from the flange 10, the said member being fastened` -to the lining 9 by the pivotal'bolt 4() and at its opposite end by a bolt 47.

Thus far we have been describing the latch and its cooperating parts that may be used on the upper door. The latch used on the lower door is exactly the same as that de?f scribed on the upper door. However the part that engages the lip 43 of the latch for the lower door is different. Attention lis called to the fact that a horizontal member 48 ext-ends across between the inner flanges 5 of the frame A, said member having its ends preferably spot welded to the -said flange. This member 48 has its'/ upper and lower edges 49 turned inward folr giving the member sufficient strength. It will be noted that the edges 7 of the doors 1 and 2 form a space between them and a suitable curved member 50 is located in this space. The free end of the member 50 lies in the proper position for the lip 43 of the latch 39 to engage,

the angular opening -iange 7 to form a stop for 'the doors,`the

--ber 48 is located inside of the doors and isL `supported in such aposition that it does not interfere with the closing of the doors, while at the same time it furnishes a support for .the curved member 50. The member 48, it

will be understood, gives additional strength to the frame A. I l

It will be understood that the lip 43 of the latch is of such a shape as not to make a positive fastening, `whereby when the door is pulled, it will readily. open, but at the same time the latch serves to hold the door closed.

yThe action of the latch of course is by gravity due to the weighted 'end 41.

. In my construction I desire to call attention to the construction of the handle 5l and the method of fastening it in position. The y handle is made up of three parts, the part 5l preferably is constructed of enamel and the two end parts 52. The outerl ends 53 have their inner sides hollow to .receive the .ends of the part 51.while the inner ends 54 arating elements for the lining and the door against which the screws will tightly clamp `the lining and door and the inner ends of the parts 52.

Attention is directed to the fact that the outermembers 1 and 2 of the doors may be ldetached from the lining 9 by loosening the bolts l1 and 5,6, which will permit the outer parts or panels to be removed, by sliding them outward, the opening 58 having its outer end 59 open to permit the pintle 21 to pass. through it.

For the purpose of strengthening the lower portion of the inner wide flange 5 of the frame A a cross member similar to 48 will preferably be applied to that portion of the frame.

Instead of forming the doors with the said flange may bei omitted, in which case the frame A will have its flange 5 with a tapered bend 6 made at .a distance from the part 3 equal to the thickness of the door,` as shown in Figure 8. In such construc- .ope'ning for the purpose described.

tion the inner edge of the door will engage the part 6 as will be'readily understood for forming a limit tofits inner movement.

In Figure 1 the side wall 60 andthe top 61 will of course be constructedas is usual 1o in ovens, and the part15 will be fextended" to the left'any' desired distance in making the complete range.

By reason of the cam portion 22 having the two at portions 323 and 24', the latch.

members will act at either side of the door to serve to hold the door in a horizontal position when it is open. By this it is meant andscope of the invention so longlas ltheyy are within the scope of the appended claims.
